Researchers have found that the inclusion of a third drug to commonly used dual-drug inhalers can reduce asthma exacerbations and improve control over the disease in children, adolescents, and adults with moderate-to-severe asthma. A team announced their findings from a systematic review and meta-analysis.

Data from 20 randomized controlled trials, which included a total of almost 12,000 patients, were analyzed in the study. Dual-drug inhalers used to treat asthma typically contain an inhaled corticosteroid (ICS) to reduce inflammation, as well as a long-acting beta-adrenoceptor agonist (LABA) that acts as a bronchodilator.

High-certainty evidence showed that the inclusion of a third drug to ICS-LABA combination therapy, known as a long-acting muscarinic antagonist (LAMA), reduced severe asthma exacerbations and slightly improved asthma control without an increase in adverse events. Previously, the benefits and harms of adding a LAMA to ICS-LABA therapy for asthma treatment were unclear and based off of only 1300 patients leading to weak recommendations in treatment guidelines.

"If we can reach optimal control of patients' asthma and reduce asthma exacerbation rates through the LAMA add-on therapy, patients may be able to avoid other treatments that carry a higher risk of adverse events, such as oral corticosteroids, or therapies that are substantially more expensive, such as biologics," said Lisa Kim, a clinical scholar in the Department of Medicine at McMaster and co-author of the study.

Inhaled LAMAs are currently available in separate inhalers or as three-in-one inhalers that also contain an ICS and LABA. According to the study, both approaches to administering the third drug work similarly.
